For our school's IB science classes, a chemistry student, physics and biology student need to work together to anaylize a topic.  Our topic is "sports".  For example, biology student is investigating how anti-flammatory's affect a person while running, physics is investigating the change in velocity when a baseball is hit and I am doing the chemistry part.  However, i am having some difficulty finding a suitable + rational experiment.

I had thought about doing the carbon cycle with respiration, however my teacher says that will be under biology. 

I am totally lost on what to investigate.  It cannot be somthing extremely easy.  Do you guys have any ideas for me?  Thanks

PS:  I forgot to mention i am only in 2nd yr chemistry and the most difficult type lab i have done would be a titration, so somthing wildly beyond my scope would not be feasible either.

Sports drinks - gatorade etc, composition, sweat, recovery etc.
Performance enhancing drugs - steroids etc
Swimming pool chemistry - chlorination of pools, salt water pools etc
Energy foods - calorimetry of various foods or sports supplements to determine energy content

I really like this idea.  But what will be my focus?

Will i investigate how gatorade affects sweat?

[mike]

Maybe testing the composition of the drinks and comparing this to what is lost through sweat.

How would I test the composition of gatorade?

What can i do besides looking at the ingredients...

You could chemically verify them. Though, that might be a little tuff with the equipment and reagents in a typical high school lab.

The question is, are you required to do an experiment, or just research and report?

pH
density
conductivity
total solids by evaporation
flame test
taste test
AA

Energy content of drink, how much sugar in the drink etc

Compare various sports drinks
Make your own sports drink

I need to do a full experiment. 

Mike, i don't really understand what you meant by listing all those things -_-

This is another possibility for finding a project

Google science fair projects

I don't need a "project".  I need an experiment.  Making my own sport drink is not what i'm trying to do.  The type of experiment i'm looking for would be like "how does the pH of acid rain affect different parts of the world?"  I would then create different acidic solutions and put them on rocks and see how they are affected.

A science fair project consists of experiment(s) that are presented in the appropriate format. I assumed you could look at many of those projects and find one that matches or nearly matches your needs. Then you could use that information to design your own work.

These are some tests you could do on the sports drink.

You DO need a project because you are NOT doing an experiment that hasn't been done before.

Making your own sports drink could be part of your project!

If you can't put together an experiment from all of the help here then you are just going to have to copy a project from the internet or something.

The thing is with a sports drink, the main component is water, so I can't really re-create a sport drink.  This experiment does not need to be somthing totally new.  It can be any type of experiment easy to do that is related to sports.
